There are several problems with that 1. ACPI tables are software and provided by the vendor with licenses that forbid modification, redistribution etc. 2. For that matter if you live in the USSA then they probably disallow disassembly 3. Its not something the average user can do > So what do I tell my helpless user? > 1.

If the DSDT bug is known then it becomes practical to look at the problem and make the Linux code bug compatible with Windows - and a fair bit of that has occurred, or to blacklist the ACPI support using the dmi table. That much becomes workable for users because it then just works out of the box. The other approach in the US is probably the "you said it supports ACPI but it's invalid class action lawsuit" approach. But I doubt that really fixes anything but the lawyers swimming pool.
